SPECIFICATION forming part of Letters Patent No. 718,254, dated January 13, 1903.

Application filed January 29, 1902. herial No. 91,768. (No model.)

9 at whom it may concern:

Be it known that we, JAMES INGHAM, J o sEPH-PoULsoN, and JOHN W. Moons, citizens of the United States, and all residents of as sand combined with a suitable adhesive substance; and it involves a vertically-disposed flask and pattern with a number of stamps arranged to Work between them.

The present invention relates to various improvements, particularly in the manner of feedingthe material and of drivingthe stamps. This specification is a specific description of two forms of the invention, while the claims are definitions of the actual scope thereof. Reference is to be had to the accompanying drawings, forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the machine with parts broken away and in section. Fig. 2 is a sectional plan on the line 2 2 of Fig. 1. Fig. 3 is a rear elevation of the derrick. Fig. 4 is a plan view of the distributer. Fig. 5 is a detail section on the line 5 5 of Fig. 1, and Fig. 6 is a sectional elevation of a modified form of the invention.

The fixtures in which the pipe mold is formed comprise a pattern 10 and an outer wall or flask 11, these being mounted on the table -12 and may be adjusted to proper position by abutments 14, which are themselves adjustable radially in the slots 15 in the table. The table 12 may be either rotary or oscillatory; but in the present instance (see Fig. 1) it is shown as rotary, 16 indicating a central pivot turning in a socket 17 in the base 5 of the apparatus.

18 indicates carrying-wheels, on which the I table 12 is mounted, and 19 indicates a bevelgear running on an inverted crown-wheel 20 V on the table 12, whereby to impart rotary 5o movement to the table. The gear 19 is carried on a shaft 21, which is geared with the primary movement or drive shaft 22. (See Fig. 1.) On top of the pattern 10 is the distributor for the sand or other material used to form the mold. This distributor is formed of a number of tangential arms 23, fastened toa central part or hub 24. These arms 23 sit loosely on top of the pattern 10, and the hub 24 carries a sectional block 25, which loosely encircles the neck of an eyebolt 1O on the pattern. (See Fig. 1.)

23 indicates an arm fastened to the distributer to hold it stationary, and this arm is itself carried by a part 28 of the derrick to be hereinafter described. The sand is fed down on top of the pattern, and as the pattern turns it causes the sandto work along the arms 23 and to be thereby fed between the pattern and flask.

Erected between a suitable support 26 and a sustaining-bracket 27 is a vertically-turning derrick 28, which has a hollow trunnion 29 at its bottom and a similar trunnion 30 at its top. Through the hollow trunnion 29 passes vertically a shaft 31, which is geared with the shaft 22 and extends up into the derrick 28,. for a purpose which will be hereinafter described.

32 indicates a hopper, the mouth of whiph passes through the hollow trunnion 30, and into this hopper the material forforming the mold is charged. The device for carrying the material to the mold will be hereinafter described.

33 indicates a horizontal arm projecting out from the derrick 28 and carrying rigidly a vertical pipe 34. Mounted to slide on this of one of the disks 41 is provided (see Fig. 2) with a spur-gear 43, and this gear is in mesh with a gear 44 on a shaft 45, which is geared with the shaft 31, before described. This mechanism imparts a vertically-reciprocating movement to the pipe 35, causing it to row slide on the pipe-section 34. The pipe-section 34 extends above and below the arm 33 and carries fast a disk 46. Over this disk is arranged a disk 47, which is adapted to be turned around the axis of the pipe-section 34 and provided with gear-teeth 48, meshed with a pinion 49 on a hand-shaft 50. The hand-shaft 50 is mounted vertically alongside the arm 33, and by turning this shaft the disk 47 may be adjusted on the disk 46. The disk 46 is formed with radial slots 51 therein, and the disk 47 is formed with areshaped slots 52 therein, these arc-shaped slots being one for each slot 51. The slots 51 have blocks 53 fitted to slide therein, and through these blocks extend rigid guide tubes 54, these tubes passing through bosses formed on the blocks 53 and these bosses lying snugly in the slots 52. When, therefore, the disk 47 is adjusted around the axis of the pipe-section 34, the blocks 53, with their attached guide-tubes 54, are moved in and out along the slots 51 through the action of the arcshaped walls of the slots 52. This allows the tubes 54 to be adjusted to the size of the mold to be formed. Fitted closely within the guide-tubes 54 are the stamps 55, which extend downward into the flask between the core 10 and the outer wall 11. These stamps 55 extend loosely through guide-brackets 56, mounted radially adjustable on a disk 57, carried by the lower end of the pipe-section 35 and braced thereon by means of rods 58.

56 indicates screws for adjusting the brackets 56, such screws passing through radial slots 57? in the disk. (See Fig. 2.) The brackets 56 also carry electromagnets 59 and may be moved in or out with the magnets to accommodate the position of the stamps. These magnets are connected with brushes 60, which run on a make-and-break switch 61, connected with the crank-disks 41, before described. By means of this switch the magnets 59 are alternately energized and denergized. \Vires from a suitable source of electric energy are connected with the magnets, the electrical connections being shown in Fig. 1.

Carried by the derrick 28 and running horizontally over the arm 33 thereof is a conveyerbox 62, in which is located a horizontal endless conveyer 63. This conveyer passes under the hopper 32 and is driven by a chain 64, passing around a sprocket-Wheel on the shaft 45, before described. The conveyer 63 carries the sand or other material to and dumps itinto the pipe-section 34, from whence it passes through the pipe-section 35 down onto the distributer-section 23. 65 indicates a gate which is mounted on the box or casing 62 and which may be adjusted vertically over the upper run of the carrier 63, whereby to regulate the material passing into the tube 34.

In the use of the invention the sand or the mixture thereof which is used to form the mold is charged into the hopper 32,from which it flows out on the conveyer 63, this conveyer dumping it into the distributer 23, which finally discharges it into the flask. The regu' lar rotation of the crank-disks 41 imparts a rocking movement to the lever 38 and acousequently vertical reciprocation to the tubesection 35 and disk or frame 57. The makeand-break switch 61 works in unison with these parts, and as the disk 57, with the magnets 59, reaches its lowermost position the magnets are energized, thus attracting the metallic stamps 55. As the disk 57 rises the magnets lift with them the attracted stamps, and when the disk 57 reaches its uppermost position the magnets are denergized, thus allowing the stamps to fall. By these means the stamps are dropped regularly into the flask and are caused to pack down the material therein, thus making a compact mass of the same. Meanwhile the table 12, with the flask and pattern, is turning continuously, so that the packing of the stamps is uniform. It will be observed that the stamps are automatically adjusted to the continually-rising height of the material in the flask, and in this connection it should be explained that the tubes 54 should be of such length that the stamps are never disengaged therefrom.

Fig. 6 shows an arrangement in which the flask or pattern is made to oscillate around a vertical axis, and in this case the distributer is caused to be rotated so that the material worked will be properly distributed into the flask. In Fig. 6, 66 indicates a hub fastened to a shaft 67 and carrying arms 68, which are similar to and take the place of the arms 23, before described. These arms 68 work over a horizontal disk 69, which is rigidly supported by hangers 70 from the arm 33, before described. The shaft 67 is geared with a shaft 71,arranged horizontally, and this shaft in turn is driven by suitable gearing from the shaft 31, before described. 72 indicates a frusto-conical deflector, which is arranged directly under the disk 69 and which slants outward to the outer periphery of the pattern 10. The material forming the mold falls through the pipe-sections 34 and 35 onto the disk 69, from which it is swept by the arms 68, and it then slides over the deflector 72 and falls into the flask. In other respects the operation of this form of the invention isthe same as that previously described.
